When you compose, it appears as plain text. When you send, Opensense transforms it into your full signature design. See [What is the Opensense signature block?](https://help.opensense.com/docs/what-is-the-opensense-signature-block) To set it up, for each email app and device you send email from: 1. Open the Opensense notification email, then highlight and copy the entire signature block (the "raw signature"). 2. Open the app below, paste the signature block into its signature settings, and make it the default. ## Things to keep in mind :::caution[When your signature won't transform] - **Viewing emails in your Sent folder.** Opensense signatures appear "un-transformed" in your Sent folder. When you reply to or forward an email from the Sent folder, the un-transformed signature block on the original sent email is removed. - **On some versions of Outlook, [out-of-office replies and calendar invites](https://help.opensense.com/docs/ooo-replies-and-calendar-invites-in-o365).** - **Sending an email to yourself**, for example from `jane.doe@abc.com` to `jane.doe@abc.com`. - **Sending an email to your own email alias**, for example from `jane.doe@abc.com` to `jane@abc.com`. - **Sending an email to a linked personal email in the iPhone app.** The iPhone app can **transfer** emails between linked email addresses, so the email doesn't pass through Opensense, and **won't** transform. ::: If you have any questions, contact [help@opensense.com](mailto:help@opensense.com). ## Desktop apps
